EXCERPT:
1. Move the machine to a smooth horizontal location. Move the machine away from other machines and personnel. Lower the blade to the ground. Lower the boom, the stick and the bucket to the ground. Stop the engine.
2. Put chocks in front of the tracks and behind the tracks.
3. Raise the blade for tests and adjustments. Properly support the blade.
Note: Unless a system test requires the front of the machine off the ground, do not stop the engine with the front of the machine off the ground. Lower the machine to the ground and stop the engine.
